318 FAMILY X. PSELAPHID^. 



Antennae with second joint small, oval ; third and fourth smaller, obconical ; 

 joints 5-8 larger, subglobular, equal ; ninth to eleventh transverse, forming 

 in male a densely pubescent club, three times as thick as eighth joint and 

 as long as the five preceding together; in female the club is smaller, less 

 pubescent and the preceding joints equal and cylindrical. Thorax sub- 

 globular, the basal groove sharply denned. Elytra each with a discal 

 groove on basal two-thirds. Front trochanters with a slender spine. Length 

 1.8 mm. (Fig. 149. <?.)

 cluding between them two-fifths of the width of segment.
